The pregnant model owns a beautiful estate in the countryside with stables for her beloved horses – the same stables where Kieran admitted to having sex with her best friend Jane Pountney.
According to The Sun, the star now wants to move on from the £2 million luxury property and find somewhere new.
A source said: "Katie could give birth any day now and is determined for her children to be brought up in a happy household.
"She wants a fresh start and to forget about what happened. This sale will be a big part of that."
Katie, 36, was left devastated in May when she discovered Kieran had been sleeping with Jane behind her back. She accused them of carrying on for seven months, starting shortly after she gave birth to son Jett in August.
The star is now pregnant with her and Kieran's second child.
Katie initially vowed to divorce unfaithful Kieran but in recent weeks signs have been pointing to the possibility of a reconciliation in the future. Katie said on her Fubar Radio show this week that she'd take Kieran's surname if he proved himself.
